LAM]? SUPPORT.

Application filed February 27, 1924. Serial No. 695,487.

The ob'ect of this invention is the manufacture a sliding arm for postsfor use in bridge, table, floor lamps or the like. The bracket arm isheld in any desired position by means of a spring member which pressesagainst the post, the spring being provided with arms which serve torelease the spring pressure so that the arm can be moved up and down.

Fig. 1 is a side elevation of the device applied to a post.

Fig. 2 is a front elevation of the same.

Fig. 3 is a plan view of a form ofv spring with arms used in the device.

In lamps of this character it is desirable not only to be able to movethe bracket arm carrying the source of light in a horizontal direction,but in a vertical direction as well, so as to adjust it to various chairheights. A device for insuring such adjustability must be easily andreadily manipulated from any position and from any angle.

In Fig. 1, 1 is the post of any lamp support, such as a bridge lamp, ora standing or table lamp and 9 is a bracket arm with socket memberswhich can be of any preferred form. The arm is supported by two ringmembers 7, connected by a plate 8, permit-ting the insertion of a spring3, having two wings 4 between the post and the plate, for purposeshereinafter set forth.

The rings and consequently the attached bracket arm supporting thesocket members are normally held securely on the post at two points bymeans of the pressure of the inner surface of the arms 2 of spring 3,the outer surfaces of the arms bearing against the inner surface ofplate 8. Except when they are rigidly held by the spring pressure therings 7 and the attached bracket arm are adapted to slide easily up ordown on the post 1. It is only necessary to press the wings l of thespring 3 backward to release the pressure of the arms from the post inorder that the rings and consequently the bracket arm and socket may bemoved up and down.

From the above it will appear that the adjustment member can be readilymanipulated from any position, a simple pressure of the thumb and fingeron the extended wings being sufficient to release the holding device.When the pressure on the wings is released, that is when the thumb andfinger are re moved, the arms of the spring bear against the post at twopoints and maintain the holder and bracket arm at the desired height. Inaddition to these features the rings and the bracket arm can be turnedin a horizontal direction at all times.

I claim:

1. An adjustable lamp support comprising a post, a member encircling thepost and slidable thereon, a lamp bracket attached thereto, and avertical spring lying between the sliding member and the post andprovided with horizontal arms extending beyond the post adapted torelease the spring pressure when bent backward to permit the slidingmember and bracket to move freely on the post.

2. An adjustable lamp support comprising a post, a member slidablethereon, a lamp bracket attached thereto and a vertical spring acting onthe sliding member, the sliding member comprising top and bottom ringsencircling the post and a vertical plate connecting the rings, thespring being constructed to lie between the post and the plate and beingprovided with horizontal arms extending beyond the post, adapted torelease the spring pressure when bent backward to permit the slidingmember and bracket to move freely on the post.
